View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Lanxide 91-X-1060-30P is a metal-matrix composite (MMC) consisting of an aluminum-silicon magnesium alloy matrix and 30 vol.% of silicon carbide. The MMC is designed to outperform its unreinforced counterpart. It is available as sand castings with a T6 heat treatment.
